 - In Helm-based operators, when a custom resource with a failing release is reverted back to a working state, the `ReleaseFailed` condition is now correctly removed. ([#1321](https://github.com/operator-framework/operator-sdk/pull/1321))
 - [`operator-sdk generate openapi`](https://github.com/operator-framework/operator-sdk/blob/master/doc/sdk-cli-reference.md#openapi) no longer overwrites CRD values derived from `+kubebuilder` annotations in Go API code.
